Is the tone of your content relevant to your target audience? Are they getting the right message? Have you optimized your designs to suit the browsing behavior of your targeted audience?
Defining your audience provides you with a wealth of information about their demographics. In order to set up the right psychological connection with them, you must determine whether you are placing various messages, forms, calls-to-action, and graphics in a way that will appeal to your target audience.
Your target audience definition, like your business and marketing goals, will serve as a guiding light for your optimization process and CRO decisions.
